3.7HC HCAA Address Register (HCHCCA)

The HC HCAA address register (HCHCCA) defines the physical address of the beginning of the HCCA. HCHCCA is shown in Figure 8 and described in Table 8.

3.8HC Current Periodic Register (HCPERIODCURRENTED)

The HC current periodic register (HCPERIODCURRENTED) defines the physical address of the next endpoint descriptor (ED) on the periodic ED list. HCPERIODCURRENTED is shown in Figure 9 and described in Table 9.

Bit	Field	Value	Description
31-4	PCED	0-FFF FFFFh	Physical address of the current ED on the periodic ED list. This field represents bits 31-4 of the
			physical address of the next ED on the periodic ED list. EDs are assumed to begin on a 16-byte
			aligned address, so bits 3-0 of this pointer are assumed to be 0. For the restrictions on physical
			addresses, see Section 2.7.
